Built for Dodge Ramcharger and Plymouth Trailduster owners who want an aggressive stance with serious ground clearance — this 4-inch lift kit raises your truck's front end to match the rear for a leveled, flush look. You'll fit up to 35" tires while maintaining factory-like ride geometry through a raised steering arm that keeps caster and other angles dialed in.
Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.
What's included
- Front and rear lifted leaf springs — durable components that raise your truck's ride height without sacrificing ride quality or performance.
- N3 shock pair (front and rear) — 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rods and 54mm bodies for a blend of off-road capability and smooth highway comfort.
- Dana 44 steering block — keeps your steering geometry at optimum angles for a factory-like ride even after lifting.
- U-bolts and installation hardware — everything needed to secure your new suspension components.
- Spring bushings and sleeve kit — engineered for your truck's specific suspension mounting points.
Important notes
- Does NOT fit models equipped with a Cummins diesel engine.
- ONLY fits models with Dana 44 front axle.
- New rear leaf springs replace your factory-equipped block.
- Proper wheel backspacing is required to safely fit 35" tires — confirm offset and backspacing before installation.
